A Money Box investigation has discovered that tens of thousands of university students in England, Wales, and Northern Ireland have been forced to pay back millions of pounds in overpaid maintenance loans. The Department for Education says any money owed due to overpayments by the Student Loans Company, should be taken back from students whilst they're still at university except in exceptional circumstances. This can leave them receiving little or no money for months at a time, with very little notice.

Binary options are a bet on whether the price of a commodity like gold or silver will be higher or lower at a certain time. The answer either 'yes' or 'no' and if you guess right you make money - if you are wrong you lose money. Earlier this year the FCA banned the sale, marketing and distribution of binary options to retail consumers as the potential for loss was so great - not to mention the possibility of fraud. So is there ever such a thing as a genuine binary option? And can you get your money back if you fall foul of a binary option scam?
